[Experimental studies for the hygienic standardization of Lasso in water].
Experimental hygienic-toxical study was carried out on amide herbicide lasso, aiming at its hygienic standardization in water. The studies were carried out in three aspects for the determination of its effect upon the organoleptic qualities of water, on the sanitary regime of water-reservoirs and toxic effect on organism. Threshold and subthershold concentrations of the deleterious effect on colour, small and taste of water were determined as well as on B0N5, on sanitary-indication microflora and on cold blooded organisms. The toxicological parameters for acute, subacute and chronic oral toxicity on albino rats were established. On the base of the experimental studies, differentiated hygienic norms (MAC) of lasso were elaborated in the three categories water-reservoirs - I mg/1 for I category and 5 mg/1 for II and II category.
